The hardness and wear resistance of amorphous Al–Mn alloy coatings can be improved by incorporating ceramic particles into them to extend their application. In this paper, Al–Mn/WC composite have been prepared with electrodeposition in stirred AlCl3–NaCl–KCl–MnCl2 molten salts at 180 °C the addition WC particles. effects stirring speed (400–700 rpm) cathode current density (15–75 mA/cm2) on pro...

This work presents RPM, a scalable anonymous communication protocol suite using secure multiparty computation (MPC) with the offline-online model. We generate random, unknown permutation matrices in secret-shared fashion and achieve improved (online) performance lightest overhead for clients compared to state of art robust protocols. Using square-lattice shuffling, we make our scale well as num...

This study examined the relationship among personal network characteristics, gratification-utilities and the frequency of use of three interactive communication technologies (landline telephone, email and instant messaging).A conceptual framework is presented, providing a rationale for three hypotheses predicting positive relationships between personal network characteristics (size, intimacy an...
